Stress Analysis of Steel Structure Comprising Cylindrical Shell with Billboard Tower
(Univ Osijek, Tech Fac, Slavonski Brod, 2018)
In accordance with EN1993-1-1, in the definition of element classes, the tubular cross section elements are considered as class 3 for cross section that respects the relation: d/t lt = 90 epsilon(2). If for any cross ...
Numerical simulation of tensile testing of pe 80 polymer specimens
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
The aim of this paper is to present the behaviour of specimens made of polyethylene material PE 80, subjected to tensile load until failure. Measurements of the temperature distribution have been done using the infrared ...
Numerical analysis of stress distribution in total hip replacement implant
(Institut za ispitivanje materijala, Beograd, 2017)
Total hip replacement implants represent permanent implants and require large bone and cartilage removal during implantation. Revision would affect joint capability to sustain load, which makes this procedure irreversible. ...
Određivanje vrednosti unutrašnjeg pritiska koji će dovesti do plastične deformacije na modelu račve / Determination of internal pressure value causing pipe branch model to plastically deform
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
Složenost geometrije posuda pod pritiskom obično predstavlja uzrok pojave koncentracije napona i deformacija. Savremeni pristup analize stanja napona i deformacija uključuje numerička i eksperimentalna ispitivanja. Svako ...
